Quebec-based satellite emissions monitoring company GHGSat has deployed three more satellites, expanding its constellation to nine, the company announced on April 15.

The GHGSat-C7, C7 and C8 satellites were deployed during the SpaceX Transporter-7 rideshare mission from the Vandenberg Space Force base in California.

In 2022, GHGSat's other six satellites observed over 500,000 facilities, detecting 179mn metric tons of CO2 equivalent in emissions, up 25% from the amount in 2021. With nine satellites now in orbit, GHGSat expects to double the volume of emissions measured this year.

“Today’s launch is another major step in growing our world-leading constellation," GHGSat CEO Stephane Germain said in a statement. "Our customers have been clear in their desire for more frequent monitoring at more sites from space, and these three additional satellites directly answer this need. GHGSat continues to establish itself as a trusted partner and provider of the best methane emissions data available."

GHGSat will launch three more payloads hosted on third-party satellites later this year.
